Additive Tackifier Agent for Water-Soluble Lubricants

ABSTRACT

A composition for an aqueous tacky lubricant, specifically targeted towards increasing lubricant retention to the moving components of chainsaws. More specifically, the composition includes a novel additive composition for environmentally-neutral lubricants. The ideal function of the composition would be to increase the adhesive qualities of an aqueous lubricant without compromising the coolant and lubricant roles of such a substance. To accomplish this, the composition includes an additive compound, that is made of a linear anionic polyamide and a cationic surfactant. The reaction between the linear anionic polyamide and the cationic surfactant creates a viscoelastic tackifier that helps the lubricant to cling to a moving chain thus preventing the lubricant from flinging off the chain when in motion. In other words, the additive compound is a tackifier agent, presented as novel both as an independent composition and in addition to extant lubricants.

The current application claims a priority to the U.S. provisional patent application Ser. No. 63/066,594 filed on Aug. 17, 2020.

FIELD OF THE INVENTION

The present invention relates generally to a composition of a viscoelastic tackifier for conventional environment-friendly lubricants, specifically in relation to optimum operating conditions for chainsaws and the like.

BACKGROUND OF THE INVENTION

To ensure proper function, chainsaw chains and bars must be continuously lubricated to avoid excessive mechanical wear on the interconnected elements of said chain. Virtually all of this lubricant is expelled from the chain during use, flung from the chain in motion or transferred into the affected wood. This categorizes the chain lubricant as a ‘total loss lubricant’, with an estimated 70 million liters of this lubricant being released into the environment per annum. One liter of conventional lubricant oil dispersed into an aquifer can contaminate up to one million liters of potable water. Peripheral environmental hazards stemming from the use of this oil (non-biodegradable benzenes, heavy metals, etc.) may persist after initial exposure, contaminating soil for years if not decades. More immediate concerns of adverse health effects caused by prolonged exposure to vaporized petroleum lubricants have also been noted; workers may suffer increased incidences of metals poisoning and cancer.

In response to the clear environmental hazards posed by the use of conventional petroleum-based lubricants, the demand for environmentally-acceptable products is growing rapidly. One potential alternative is the use of environmentally-neutral water-soluble lubricants produced from vegetable products. Essential features of these environmentally-neutral compounds are non-toxicity and rapid biodegradability, preventing extended contamination of a working area in the event of a spill (or regular loss of lubricant during use). In tandem with the use of more environmentally-friendly compounds for lubrication, battery-powered equipment tools are becoming more popular among operators concerned with noise or atmospheric pollution. It follows, then, that these new tools would require a novel form of lubricant to maximize the efficacy of the electrically-powered tools. Thickening agents added to conventional lubricant compositions, may be extracted or derived from chitin, chitosan, dextrin, cellulose, starch, vegetable gums, hyaluronic acid or derivatives and/or mixtures thereof. Though this additive may decrease viscosity, they do not appreciably increase lubricant retention to the chain. As previously outlined, the high-speed circulation of a chain is liable to shed lubricant at an excessive rate if not properly applied, thereby robbing the chain of essential lubrication.

The present invention comprises a novel additive composition for environmentally-neutral lubricants, specifically targeted towards increasing lubricant retention to the moving components of chainsaws. The ideal function of the present invention would be to increase the adhesive qualities of an aqueous lubricant without compromising the coolant and lubricant roles of such a substance. To wit, the additive compound is a tackifier agent, presented as novel both as an independent composition and in addition to extant lubricants.

DETAIL DESCRIPTIONS OF THE INVENTION

All illustrations of the drawings are for the purpose of describing selected versions of the present invention and are not intended to limit the scope of the present invention.

In reference to FIG. 1 through FIG. 4, the present invention is a composition for an additive agent that may be added to a water-soluble lubricant, so as to improve the adhesive quality of the lubricant. In other words, the present invention comprises a novel additive composition for environmentally-neutral lubricants, specifically targeted towards increasing lubricant retention to the moving components of chainsaws. The ideal function of the present invention would be to increase the adhesive qualities of an aqueous lubricant without compromising the coolant and lubricant roles of such a substance. To wit, the additive compound is a tackifier agent, presented as novel both as an independent composition and in addition to extant lubricants.

The following description is in reference to FIG. 1 through FIG. 4. As seen in FIG. 1 through FIG. 3, the present invention is a composition for a lubricant additive catered towards improving the adhesive property and tackiness of water-soluble lubricants. To accomplish this, the composition of the present invention comprises a quantity of an anionic linear polyamide, a quantity of a cationic surfactant, and a quantity of a water-soluble lubricant. According to the preferred embodiment, the quantity of the anionic linear polyamide and the quantity of the cationic surfactant are homogeneously mixed to form a lubricant additive. This is so that, the reaction between anionic linear polyamide and the cationic surfactant creates a viscoelastic tacky agent that helps the lubricant to cling to a moving chain of a chainsaw, and thus prevents the lubricant from flinging off the chain when in motion. In other words, the lubricant additive is a viscoelastic tackifier. Accordingly, the quantity of the water-soluble lubricant and the lubricant additive are homogeneously mixed into an aqueous tacky lubricant.

According to the preferred embodiment, the anionic linear polyamide is a compound comprising linear 2-propenoic acid, sodium salt, and a polymer with 2-propenamide. However, this compound is generally interchangeable with, or synonymous to the following:

-   -   2-Propenamide-sodium 2-propenoate copolymer     -   2-Propenoic acid, sodium salt, 2-propenamide polymer     -   2-Propenoic acid, sodium salt, polymer with 2-propenamide     -   Acrylamide-sodium acrylate copolymer     -   Acrylamide-sodium acrylate resin     -   Acrylic acid, sodium salt, polymer with acrylamide     -   Sodium acrylate acrylamide polymer     -   Sodium acrylate-acrylamide copolymer     -   Sodium polyacrylate-acrylamide resin

This proposed compound may further be represented with the molecular formula:

(C3-H5-N—O.C3-H4-02.Na)x-

According to the preferred embodiment, the quantity of the anionic linear polyamide may range between 0.001 percentage by weight (wt. %) and 20 wt. % of the aqueous tacky lubricant. Further, the quantity of the cationic surfactant may range between 0.1 wt. % and 30 wt. % of the aqueous tacky lubricant. However, more specifically, it is preferred that the quantity of the aqueous lubricant additive ranges between 0.001 wt. % and 5 wt. %. Preferably, the lubricant is water-soluble and environment friendly. To that end, the composition of the present invention comprises a quantity of water ranging between 40% wt.-98.099 wt. % of the aqueous lubricant. Thus, as seen in FIG. 2, the composition of the aqueous tacky lubricant is a combination of water (40-98.099 wt. %), lubricant additive (0.001-20 wt. %), and other compositional constituents (1.9-60 wt. %) that make up the lubricant.

In the preferred embodiment, the composition of the water-soluble lubricant most directly embodies a unique combination of dried, powdered botanicals observed to be effective in preventing hypoglycemia when delivered orally. Accordingly, the lubricant the water-soluble lubricant comprises a quantity of glycerin, a quantity of propylene glycol, a quantity of polyalkylene glycol, a quantity of polyethylene glycol, a quantity of anti-corrosive agents, a quantity of anti-wear agents, a quantity of preservative agents, and a quantity of water, wherein the quantity of glycerin, the quantity of propylene glycol, the quantity of polyalkylene glycol, the quantity of polyethylene glycol, the quantity of anti-corrosive agents, the quantity of anti-wear agents, the quantity of preservative agents, and the quantity of water being homogeneously mixed to form the water-soluble lubricant. However, it should be noted that the water-soluble or aqueous lubricant may comprise any variety of suitable solvents, and/or one or more ingredients that are known to one of ordinary skill in the art, and may be mixed in different concentrations, as long as the intents of the present invention are not altered.

According to the preferred embodiment, the preferred ranged ratios of the other compositional constituents of the aqueous lubricant are as follows. The quantity of glycerin ranges between 0.1 wt. % and 10 wt. % of the aqueous lubricant, the quantity of propylene glycol ranges between 0.1 wt. % and 75 wt. % of the aqueous lubricant, the quantity of polyalkylene glycol ranging between 0.1 wt. % and 5 wt. % of the aqueous lubricant, the quantity of polyethylene glycol ranges between 0.1 wt. % and 5 wt. % of the aqueous lubricant, the quantity of anti-corrosive agents ranges between 0.5 wt. % and 5 wt. % of the aqueous lubricant, the quantity of anti-wear agents ranges between 0.5 wt. % and 30 wt. % of the aqueous lubricant, and the quantity of preservative agents ranges between 0.01 wt. % and 5 wt. % of the aqueous lubricant. As seen in FIG. 3, the preferred ranged ratios for each compound of the aqueous tacky lubricant are outlined by weight. Further, for the purposes of the present invention, the agents listed are considered to be components of an extant lubricant compound, generic and variable across multiple embodiments, or otherwise well-known within the field. In other words, the quantity of each constituent ingredient may be varied, as long as the objectives of the present invention are not altered.

Accordingly, the variable ranges for each active ingredient are listed below:

An aqueous lubricant additive ±19.999% Glycerin ±9.9% Propanediol; propylene glycol ±4.9% Polyalkylene glycol ±4.9% Polyethylene glycol ±4.9% Anti-corrosive agents (generic) ±4.5% Anti-wear agents (generic) ±4.5% Preservative agents (generic) ±4.5% Water ±58.099%

In reference to FIG. 4, testing data for the relative tackiness of alternate compounds is accumulated and depicted. Accordingly, the data was retrieved during a ductless siphon test—wherein the subject compound is drawn up a standard capillary via controlled vacuum to form a uniform string of viscoelastic fluid. The fluid is measured for tackiness based on relative comparisons of the size of a formed contact patch and duration of said contact once the fluid is hydrated. Performance results are presented in relative terms, ‘10’ representing superior tackiness and ‘1’ representing inferior tackiness:

Sodium Carbomer 1 Cellulose 1 Gum Tragacanth 1 Sodium Acrylamide 1 Potassium Acrylamide 1 Gum Arabic 1 Gum Karaya 1 Guar Gum Cationic 1 Hydroxypropyl cellulose 1 Hyaluronic Acid: 1 Dextrin 1 Starch 1 Pectin 1 Hydroxyethyl Cellulose 1 Hydroxypropyl Methylcellulose 2 Xanthan Gum 3 Guar Gum 3 Corn Syrup 5 Maltose Syrup 5 Sugar Syrup 5 Molasses 6 Long Chain Poly (Ethylene oxide) 7 Linear 2-properioie acid, Sodium salt, 10 Polymer with 2-propenamide

Thus, from the data, it is evident that the compound [Linear 2-propenoic acid, Sodium salt, Polymer with 2-propenamide] is most suitable for this application. In other words, the composition of the lubricant additive, wherein the lubricant additive comprises [Linear 2-propenoic acid, Sodium salt, Polymer with 2-propenamide] as the linear anionic polyamide, creates a superior tackifier agent when combined with a suitable cationic surfactant. However, the admixture of other elements and extracts listed here are to be considered within the scope of the present invention for the purposes of creating alternate embodiments of the aqueous lubricant additive.
